call</p>
<p>A QDBusPendingCall object is a reference to a method call that
was sent over D-Bus without waiting for a reply. QDBusPendingCall
is an opaque type, meant to be used as a handle for a pending
reply.</p>
<p>In most programs, the QDBusPendingCall class will not be used
directly. It can be safely replaced with the template-based
<a href="qdbuspendingreply.html">QDBusPendingReply</a>, in order to
access the contents of the reply or wait for it to be complete.</p>
<p>The <a href="qdbuspendingcallwatcher.html">QDBusPendingCallWatcher</a> class
allows one to connect to a signal that will indicate when the reply
has arrived or if the call has timed out. It also provides the
<a href="qdbuspendingcallwatcher.html#waitForFinished">QDBusPendingCallWatcher.waitForFinished</a>()
method which will suspend the execution of the program until the
reply has arrived.</p>
<p><b>Note:</b> If you create a copy of a QDBusPendingCall object,
all information will be shared among the many copies. Therefore,
QDBusPendingCall is an explicitly-shared object and does not
provide a method of detaching the copies (since they refer to the
same pending call)</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QDBusPendingCall" />QDBusPendingCall.__init__ (<i>self</i>, <a href="qdbuspendingcall.html">QDBusPendingCall</a>&#160;<i>other</i>)</h3><p>Creates a copy of the <i>other</i> pending asynchronous call.
Note that both objects will refer to the same pending call.</p>


<h3 class="fn"><a name="fromCompletedCall" /><a href="qdbuspendingcall.html">QDBusPendingCall</a> QDBusPendingCall.fromCompletedCall (<a href="qdbusmessage.html">QDBusMessage</a>&#160;<i>message</i>)</h3><p>Creates a <a href="qdbuspendingcall.html">QDBusPendingCall</a>
object based on the message <i>msg</i>. The message must be of type
<a href="qdbusmessage.html#MessageType-enum">QDBusMessage.ErrorMessage</a>
or <a href="qdbusmessage.html#MessageType-enum">QDBusMessage.ReplyMessage</a>
(that is, a message that is typical of a completed call).</p>
<p>This function is useful for code that requires simulating a
pending call, but that has already finished.</p>
<p>This function was introduced in Qt 4.6.</p>

object based on the error condition <i>error</i>. The resulting
pending call object will be in the "finished" state and <a href="qdbuspendingreply.html#isError">QDBusPendingReply.isError</a>()
will return true.</p>
